IGNITION -APPARATUS FOR HYDROCARBONENGINES.

Application led'February 19, 1910.

To all whom t may concern.

Be it known that I, MILTON TIEBETTS, a citizen of the United States, and resident of Detroit, county` of Wayne, State of Michiganrhaveinvented certain new 'and useful Improvements in Ignition Apparatus for Hydrocarbon-Engines, of which the following is a specification.

' This invention 4relates to ignition apparatus for hydrocarbon engines, and particularly to ignition apparatus for the engines of motor vehicles, although some of the features are not-limited tol this particular application. M

i Tlie'ignition apparatus of a. motor vehicle is generally placed in a receptacle which is mounted on the dash ofthe motor vehicle. Inl view ofthe fact that a hood sometimes extends 'rearwardly'over the dash, itis difficult to remove the apparatus from thereceptacle since .the hood interferes. It is generallynecessary to remove the entire receptacle from thedash so that'r theapparatus may" b"ren1o\:ed therefrom.

OneY 'of the objectsof this invention is to support the ieceptacle in such a manner that it maybe niored to a position to clear't-he hood so that the apparatus may be readily removed.

Another object is to support the conductors and" connections for the apparatus insuch a lnanriei'tliat they will. be efficiently insulated. v f

Another object is to improve the apparaH tus and receptacle -inV general.

. l `urtlierobjccts will appear: from the de-` tailedl description. l

The 'invention will be descrilied .in corr m nection` with the accompanying4 dra wings. in which i i Figurerlfis a section on thehue 1"-1 Fig.

Referring to Figs. 1 to 5, 15 designates the dash of a motor vehicle, and 16 the overhanging hood. A receptacle 17 is pivotally supported, in av manner hereinafter described in detail, on brackets 518 and 19 secured to the dash, so' thug' the receptacle may swing from full to dotted line position shown' in Fig. 2. The receptacle is arranged to receive and support the usual ignition apparatus consisting of trembler coil 20 and transformer coil 21. The bottom wall of the receptacle is arranged to support'4 a se-V ries of contacts 22, 23. 24, 25 and 2G and the coils are removably supported in the` receptacle and. provided with a series of contacts cooperating with the contacts 22 to 26, inclusive, this particular construction being shown and described in patent toHuffV to the bottoln'wallv of the' receptacle, by con- A ro-V 27 and another bracket 28, also mountedon and secured to the wall-'of the receptacle.

This switch comprises a cylinder of insulti-t# Ving material providedx'with contact seg-y ments 30, 31' and 32. A pair ofbrushes 33, 'l

and 34* "are supported on a bracket 35, (Fig.

2) which is mounted upon the dash of the vehicle. These brushes are electrically con.

nected to the battery 33 and the magneto 3l by conductors 33" and 34h, respectively, passing through and supported by the bracket 35. al'e supported -from the bottom wall ot thc ,.i'eceptacle, and are arranged Ato bear upon the rotary switch 29. As shown in Fig. 3, the brushes 25 'and 26 are electrically connected tothe contacts 25 and 2G,4 respectively, while the brushes 22 and, 2 are electrically connect-ed to the contacts 22 and 225 respectively. '.lheai'iangement ot' the brushes and their relative positions with re- ,spect to the contact segments on the switch shown in Figs. 1 and 4. A pivot pin 27,

for Switch 29, is provided with a flange iwhich constantly bears on and has an cle'ctrical connection with the metallic bracket' 27. This pivot is mounted in a metallic bearing 3G of the bracket 18, which is of insulating material. The segment 32 is provided witli an extension 38 forming a pivot, which is mounted in an bearing 38" of conducting material. 'lhediearing members 3'6 and 38a have similar extensions throngl: brackets 18 and 19, the extension .on ineinbei' 38a appearing in Fig. 2. The bearing member 38 is electrically connected to a distributer 40 by means of a suitable conductor 39.. The connection between the parts 39' and 38 is 'preferi'ibly made by a plug switch arrangement 41, and the connection between the conductor 37, which is grounded and the member 36 is niade by a similar plug switch 41. The distribntei' 4Q`lis arranged to successively connect the s/paik plugs fl" of the liydiocai'lmn engine cylinders in a manner well known to those skilled in the art. ln this particular em bodiinent, the invention isshown as applied tola four cylinderrngne andtheI relative 4:position of the listributer .is shown in the 'diagi'ai'ninatic-r l tion of Fig. 2.

The switch --29 hasy scoured thereto a toothed segment 42,' which is arranged to mesh with a rack 13 guided in the front wall ofthe receptacle. The rack is operated by means of a button 44, the shank of which works in a slot 4G in a plateO. The slot (seeFig. 5) is provided at its ends with depressions `47 and at an intermediate point with .another notch or del'iiession, all three of said depressions being adapted to rcccive the shankof the button which is pro vided with a spring 45, so 'as to latch the button and rack in .the different positions. 'llie button has formedthereon a lug 4S, which is arranged' to be engaged by thc bolt of a. lo't'ik 4-. i

The receptacle 17 is normally secured in place agaii'tst Jthe Vdash by means ofthe clamping putsi-52 and brackets 5.1.' When it is desiredto remove or replace the coils in the receptacle, tli-ccla|iipiiignuts are loos Brushes 25, 26, 22" and 23"' cned and the receptacle swung about the pivots 2.7 and 38 to. dotted line position shown iii Fig. 2. In this position the top of the receptacle will clear the hood 1G and, therefore, the coils may be readily removed. It will be noted that the pivots 27 and 38 are so arranged relatively to the receptacle 17 that the center of gravity of the receptacle will. fall rearwardly and forwardly of the pivots when the receptacle is in the dit ferent positions shown in Fig.- 2.

The operation of the switch 25') is similar to that shown in the'Iatent No. 838,251 referred to.

In order to connect the magneto in circuit, the button 44 is moved downwardly to the lower depression t7 or to Mag7 position. This will move the rack 48 downward, thus rotating the toothed segment 42 and thereby turning the switch 2S), so that the segment 3() will be in a position to connect the brushes 26 and 34", which are side by side as shown in Fig. 4. At the saine time the segment 32 will be moved into contact with brush 23 (Figs. l, 2 and l). tension curl-cnt will thon pass troni thc inagnclo 'by means of connection 34') to brush 3l, 'then through segment 30, brush 2G -to 'contact 26, which connects tothe primary of the transformer, Contact 2t, connection 24 to bcaring'C-l, plug 4l and connection 37 tol The high tension circuit will he' ground. made through the spark plugs', distributor 40, connection Bt), bearing member HS, pivot 38, segment 32, brush 23, contact 23, the secondary of the transformer, contact 24, connection 24., bracket 27, bearing 3G, Vplug 4l, connection 37 to ground. i

ln ordcr to throw the battery in circuit, llic button 44 moved to causo. ,ts shank to cuter the upper notch 47 or to Ilat posi tion. lhrough rack 43 and toothed segment 42, this will rotate the switch 2S) to cause the segment 25() to connect brushes 33 and 25 (Fig. 4:). and turn segment 32 into position to contact with brush 22, The. connections may be traced in a manner similar to-tha't for Vthe magneto connections. When the-battery is in circuit the segment 31 (Fig.l 1) will connect. thc brushes 34 and 24 (Fig. 4) so that the magneto is short-circuitcd. That is,

the circuit for thcniagneto will be from ii'iagneto by connection 5H to bruslifilt, Sogincnt 31., brush 24, connection 24", bracket 27, to bearing 36, plug 41, connection 37 to ground.

/1 v position the buttonjtfJf is moved to bring its shank into the intermediate notch o'r depressionl or to otfft posit-ion. Thisywill disconnect both the-'battery and the magneto alud .1.20 .ln order to throw the switch to neutral i sa 00v readily removed when-said receptacle 17 is i enough so that mounted in `the subbase is secured to @these brackets through the 31this segmentl subtending a greater angle than the other segments, so that it remains in Contact with the brushes 34 and 24; whether the switch button Mis in Bat or oit position. i

The segments 30, Bland 32 `are made long the connections of the apparatus will remain undisturbedhthat is, the segments will remain in Contact with the brushes `with which -they Yare engaged during the movements oi the receptacle to operative and inoperative positions. It will be noted that the movement at the circumference ofthe switch will be relatively small.

By placing the switch outside of the box the coils can ybeplaced close together, so'that thesize oi the receptacle is very much reduced. The plate ,50, which. extends downwardly from the receptacle, forms a pro tective covering for the switch mechanism located below the receptacle. It is obvious thatthe receptacle maybe extended downwardly so as to cover the switch at the sides and bottomfas `well as at the end. p The highutension connections, which re-f qulre `the mostcareful insulation due to the high voltage and due to the fact that one of the high Y,tension terminals is grounded, are brackets so that they may be carefully insulated from the ground*that is,fron1 the motor frame. tension circuit is thus soA designed that the insulation will be a. maximum. The low tensionterminals are mounted in a separate bracket whichenables the connections to be convcniently made, andfwhich keeps the low tension wires at a safe distance from the high. tension wires so that they may be thoroughly insulated from each other.

In the construction show'n in Fig. 1,'the

brackets' are shown as mounted upon` and secured to 'the dash. These brackets may, however, be mounted upon a subbase, which the' dash. rllhe indi-l vidual bracketsyform in fact together, one bracket having av plurality of bracket arms.

Another in Figs and 7. In this form the recep` tacle is mounted so asto swing on a vertical axis. The brackets 18 and 19 are securedto the dash as in the construction `shown in F ig. `1, `and the receptacle is mounted lupon rotatz'tble. switch 29. In vthis construction, howeve'r,the bracket 35, which carriesthe low vtension wires and brushes, 1s secured to ijn the dotted line The receptacle is tion against the dash by means of a clamping nut 60, engaging aslottedv bracket 61'on position shown in Eig., 7.

Another form of this invention is shown in Figs. 8, 9 and 10. The arrangement of the coils and switch in thisform is similar to that'shown in Patent No. 838,251 referred been given the reference charactersof parts in the above patent with an exponent added. therein a A bracket 71 of insulating material is suitably secured to the receptacle and supportsr the switch 1.7!. A. downwardly extending portion 71 of the bracket 71 (see Fig. 10) has secured thereto a plurality of L-shaped members 72 and 73, which have formed thereon trunnions 74 and 75 which engage bearings in arbracket 76.

bracket 71. The brushes are arranged in theA same manner as shown y,

in Patent 838,251 referred to.-V A suitable connection 25" is made `from a binding" The L-shaped` vmembers 72 and 73 are of metal, while ther The provided with segments 23 which engage brushes which are f `to, and therefrne corrcsporuling vparts have and 78 to suitable spring` i 71 of the bracket while the vcoperating` contacts 81 and .82 are mounted on the Fig. 9, while the ground connection is made tov the bindingl post 83 on the L-shaped `member 72. 'A binding pgst 85 for v the ground connection. is mounted on' the bracket 76 and the shank of the binding `post isarrangedto make an electrical connection with the trunnion 74. Similarly yThe contacts Bland 82 are 105 the L-shaped memthe binding post 86 for the distributer is i .c

arranged to `have an electrical connection nections betweenv `theV manner.

It will be seen that. binding 483 and 84 form what may be termed a connecting board. In order ,that these binding posts may be, accessible, the receptacle is provided, with a removable plate 87 which is 'secured to the receptacle The relectrical con-` trunnlons and the g lnding posts may be made 1n any suitable posts 77, 78, `A

rthe front of l in the plate'ST, a ange 89a forming a stop to hold it'in position. This handle is ar.- ranged to be locked in off position by' means of a lock 90, tlieliandle having a key hole which registers with the key hole` linthe lock when the handle is in off position. The handle` has.a downwardly projectingportion 91 which covers the head of the screw S8. By means of the above construction when the plate is in place and ,thehandle 89 is locked, the ex-. tension 91 will cover the head of the screw SSVand thus will prevent removal of the plate 87 so thatvthe connecting board cannotbe tampered with.

The receptacle swings about the trunnions 74 and 75 as an axis, and is locked in position by means oi" clamping nuts 93 engagingV the slotted brackets 92. 'Y The lowei' end of the receptacle is cut away as at 94, so that the receptacle may be placed in vposition between its trunnions on the bracket T6.' It will be noted that the bracket TG extends into the receptacle.

i It is-obv-ious that various changes may be made in the details of construction without departing from `this invention, and it is, therefore, to be understood thatthis inlvention is not to be limited to the speciic construction shown and described.
